I stripped the bottom half of the plant at day 16 or so and seen no nuts. It was the bottom 3rd of the rest left on the plant that hermed. Thought I was good to go after day 16 and wasnt looking as closely anymore. Checked my garden every day though.
I just got into running cookies crosses and remembered gromer saying on insta to strip the bottom 3rd of cookies plants and then be on herm watch. It's my bad for only doing a quick 1 minute search of each plant after day 16. Wont be running any more fem cookies crosses that's forsure, or at least kitchen sink.
I wanna add that I definitely wasn't "ignoring" my garden , I run a 150gallon notill pot in a tent with multiple strains and the balls that opened were 2ft deep into the canopy which is near impossible to get into without breaking branches. Balls on the edges of the canopy were just forming and none were open. I only had 1 other herm out of the last 200+ fem seeds so I dont have experience looking for them, but I did look every day. Now I know for my next run.
If your got more kitchen sink run that shit. You just got bad luck on that one, I just finished a run from seed. I started with 54 plants of various strains after pulling some late showing males I was down to 48 plants. I had 4 plants Herm on me, I got 3 of them early but one snuck by til I saw a pollen sack on the floor. Was in middle of a row so hard to see the middle of the plant where I found the rest of them.
You might be alright anyways as I just finished trimming the plants around that one and only a few non viable seeds were found and they had a good 35 days to work on making seeds after I found and removed that plant.
I had a pack of 6 kitchen sink in the room and no herms at all, smells are amazing. Plants are taller than most other strains I ran this run, most of them look to be different phenos but have some similarities in growth as far as size. This was a hard ass run for me especially with so many different seeds and a new room. I was not easy on these plants and they took it in stride and still produced beautiful flowers. I haven't trimmed them up yet and got a while before can smoke but there are definitely a few contenders to be keepers in the kitchen sink and I'm pretty picky.
EDIT: sorry for some reason this post was up, I'm now not sure how old it was when I replied to it but I don't even see it anymore.
